INTERACTION BETWEEN PHYSICAL AND ECONOMIC GEOGRAPHY

The chairmen of the departments of physical geography and economic geography of the USSR at Moscow University call for greater interplay between the two major subfields of geography, particularly in the context of geographical research for regional planning and geographical prediction generally. The demands of a modern economy require a more integrated approach to the study of spatial systems encompassing the totality of the natural environment, settlement, production and living conditions. Such close interaction between physical and economic geography needs to be pursued at all levels of geography as a discipline, from international geographical congresses down to ordinary student field practice.

GEOGRAPHICAL CYCLES IN THE CIRCULATION OF MATTER

Natural scientists have long studied the circulation of matter within nature, and geographers have long investigated the exchange of matter between nature and man in the process of economic production. The time is now at hand to develop an overall theory of geographic cycles that would encompass the circulation of matter both within the natural environment and in the process of human activities. The author suggests an array of geographic cycles that appear to operate in the man-environment system, and shows how the identification and study of such cycles might provide a new focus for the organization of geography as a science, for geographic research and for its practical application.     

TRENDS AND CYCLES IN THE COMPOSITION OF THE FEDERAL BUDGET, 1947–48

In this study, systematic movements in the composition of the Federal budget are studied, using a simple statistical structure which distinguishes trend, cyclical, and price-indexing phenomena. Using NIA data on budget expenditures and receipts, it is found that share movements on both sides of the budget are dominated by trends. Among expenditure categories, the shares of transfer programs show strong upward trends while the defense purchases share has beentrending strongly downward. On the revenue side, the shares represented by social insurance contributions and personal income taxes have been trending upward at the expense of corporateincome taxes and indirect taxes. Significant cyclical and price-indexing responsiveness is shown by several expenditure and revenue categories. A noteworthy finding is that the estimates show little evidence of structural change over 1947-1978, suggesting that the trend and otherforces found to be significant are not of recent origin but have been at work over the whole period.     

Circles AND CYCLES

正Coming to Tibet I came to Tibet in the normal way,that is,the normal way for many of the workers and students coming to Tibet:42hours on a train from Chengdu to Lhasa.Also,like many of the workers and students,I had a ticket for a hard seat.

EMPLOYMENT CYCLES AND PROCESS INNOVATION IN REGIONAL STRUCTURAL CHANGE*

Regional employment cycles, the demand for skilled and unskilled labor, and process innovations are analyzed in the context of an industry product cycle. Employment fluctuations caused by endogenous technological change lead to spatial decentralization of production facilities through capital relocation and spatial divisions of labor. A capital investment profile suggested by the product cycle scenario is related to employment cycles. A price system for output is outlined in terms of wages and profits over the product cycle.

POST-COLONIZATION INTERACTION BETWEEN VANUATU AND FIJI RECONSIDERED: THE RE-ANALYSIS OF OBSIDIAN FROM LAKEBA ISLAND, FIJI*

PIXE–PIGME analysis of 19 obsidian artefacts from Lakeba Island in east Fiji identified contact with northern Vanuatu in the post-colonization period ( c. 2500–1000 bp ) of Fiji. The Lakeba obsidian is the only physical evidence for interaction across the 850 km water gap separating the archipelagos of Vanuatu and Fiji in the first millennium ad . New research on the Vanuatu obsidian sources with laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS) casts serious doubt on the validity of a long-distance inter-archipelago connection in the post-Lapita era. This paper presents the re-analysis of 18 obsidian artefacts from Lakeba using LA–ICP–MS and radiogenic isotope results that demonstrate that the Lakeba obsidian is not from Vanuatu, and it most likely derives from the Fiji–Tonga region. Geochemical evidence for long-distance interaction and migration between the West and Central Pacific in the post-Lapita era has yet to be identified.     

CHANGES IN THE STRUCTURE OF EVAPORATION IN THE ARAL SEA BASIN

An analysis of evaporation changes in the Central Asian plain in connection with the drop of the Aral Sea level beginning in 1961 shows that there has been a reduction in evaporation from stream valleys and deltas and an increase in evaporation from irrigated land and newly formed evaporating surfaces. These new entities are primarily the Arnasay depression (west of the Golodnaya Steppe irrigation district) and the Sarykamysh depression (west of the lower reaches of the Amudarya), which have become filled with spent irrigation water draining from the irrigated land. Another new source of evaporation associated with human activity are the lakes and wetlands formed along the Kara Kum Canal as a result of the filtration of canal water. It turns out, furthermore, that irrigation on sloping piedomon plains, such as those watered by the Kara Kum Canal, requires more water than in old irrigated alluvial plains because of the additional water needed to flush salt out of the soil and to fill subsoil cavities and raise the watertable.     

RELATION BETWEEN BUILDING DAMAGE AND GROUND CONDITIONS IN THE 1999 QUINDIO EARTHQUAKE IN COLOMBIA

An earthquake of magnitude 6.2 (M _b ) occurred in west-central part of Colombia on January 25, 1999. This earthquake is officially called Quindio Earthquake from the name of the most affected province. The earthquake caused disastrous damage to a large number of buildings resulting in significant casualties. In Armenia City and its neighbouring villages close to the epicentre over 1000 people were killed by the earthquake and the total monetary loss reached US$ 2 billion. Armenia City, which has an approximate population of 280 000 people, apparently suffered the worst in terms of casualties and damage to the buildings.

The present paper focuses on the causes of damage to houses and buildings in Armenia City. First, the evolution of the urban area of the city was investigated using historical features available maps from each era. Then a correlation between buildings damage and topographical features of the city was studied. The effects of geological features and amplification of ground motion were also investigated.     

ON THE RELATIONSHIP BETWEEN SECTORAL AND SPATIAL MANAGEMENT IN THE ELECTRIC POWER INDUSTRY OF THE USSR

The management system of the electric power industry of the USSR operates at two technological levels: a lower level of 92 regional power systems, each encompassing one or more oblast-type civil divisions or a small union republic; an upper level in which regional systems are combined into 11 unified power systems, where peak loads can be more easily moved between time zones. In addition there are electric power administrations within the RSFSR and ministries within the union republics, concerned mainly with administrative functions. Power administrations often do not coincide with unified systems, creating problems of efficient electric power management. Furthermore, the boundaries of unified power systems and power administrations often do not conform to the boundaries of major economic regions, which are used for current and long-term planning of the Soviet economy. This does not necessarily mean that the power systems are out of step with the economic regions. Soviet economic regionalization theory has long stressed the important region-shaping role of electric power systems. It may well be that in some cases, the boundaries of economic regions, not the power systems, require adjustment.
